Challenges and Solutions<br />

The habitat then usually switches from a mixture<br />

of shrubs and perennial grasses to invasive annual<br />

grasses, displacing native wildlife. Where fires have<br />

become very frequent, they prevent the shrubs from<br />

returning, making this conversion to non-native grassland<br />

permanent.<br />

In other areas, suppression of wildfires allows juniper<br />

and pinyon trees to invade. When woodland habitat<br />

is established, understory vegetation is significantly<br />

reduced and fire will not carry. This eventually results<br />

in the permanent loss of sagebrush habitats and transition<br />

to permanent woodlands.<br />

These transitions from one habitat type to another can<br />

be extremely difficult to reverse and are responsible<br />

for making the sagebrush steppe less valuable to wildlife<br />

and people.<br />

Conservation Practices<br />

• Use management strategies that include part or all of<br />

the following:<br />

– Maintain or create a patchwork of native perennial<br />

bunchgrasses, forbs, and legumes, mature and<br />

young sagebrush, and open ground.<br />
